Avoiding Local System References

You should not add specific references to the local system in
the user initialization file. You want the instructions in a user initialization
file to be valid regardless of which system the user logs into.

For example:

To make a user's home directory available anywhere on the
network, always refer to the home directory with the variable $HOME.
For example, use $HOME/bin instead of /export/home/username/bin. The $HOME variable
works when the user logs in to another system and the home directories are
automounted.

To access files on a local disk, use global path names, such
as /net/system-name/directory-name.
Any directory referenced by /net/system-name can
be mounted automatically on any system on which the user logs in, assuming
the system is running AutoFS.
